I think I may have same player (it looks exactly the same & has MP4 Digital player in the same style, which was sold to me on eBay (from Hong Kong) as 2GB but turned out to be 1GB (it had been hacked I think). It stopped working after 3 days & I need to find out firmware version for it.
Would be really grateful if someone with a working player could check their player settings for this. Also, if anyone would be kind enough to use the s1clone tool from http://www.s1mp3.de
to create a raw image of the flash chip. Would be best to back up all data onto your PC, then delete everything on player flash disk otherwise file created would be HUGE!!
For info, my flash memory chip is Samsung 1GB, part no starts K9G8G..
smaller chip in middle of player is AK1022, and there is a tiny (5mm x5mm) chip near top of board SPT SP3767AHN 07DS94
Writing on case at front on top of screen is MP4/WMA/REC/AMV, with the MP4 DIGITAL PLAYER logo at bottom of screen .
Please let me know if anyone can help get full firmware file for it, flash image, or even just firmware version.
